'Stretch out the muffin top': Dannii Minogue shows off her bikini body as she enjoys a break from filming Next Top Model

However, the Australian singer suffers from body insecurities just like the rest of us as she claimed she had a 'muffin top'.

Posting two photos of her in a bikini in Barbados on her Instagram account, Dannii joked she had perfected poses to hide her imperfections.

In another image, she is seen reclining on a sunlounger while listening to her MP3 player, captioning it: 'Poolside heaven ☀ #bintm.'

When a Twitter follower expressed astonishment that Dannii would claim to have a muffin top, the former X Factor star replied: 'Ha ha #BikiniPose that conceals it well - I promise! #eatingWayTooMuchAndLovingIt.'

Dannii is currently in the Caribbean filming her first series as a judge on Britain and Ireland's Next Top Model.

Although fellow judge, American model Tyson Beckford left the island on Wednesday, it appears Dannii is staying on a few days.

The Australian was unveiled as a new judge on the Sky Living reality show in December.

She will join existing judges Elle Macpherson and Tyson, who she seems to have struck up a friendship with, dubbing him 'on set hubby' in her Tweets.

Speaking about joining the show, Dannii said recently: 'I am brushing up on my model moves and with my highest platform heels on, I am excited to come face to face with (well, maybe look up to) the glamazons of Britain & Ireland's Next Top Model 2013.

'I think it will be interesting for viewers to see me do something completely different. I can’t wait to get back on British TV and I’m not nervous at all.'
